Definitions

  • This invention relates to a filter used as a fuel filter within a motor vehicle.
  • a motor vehicle fuel tank is usually provided with a fuel filter for removing foreign matter, for example, water and dust particles, from the fuel.
  • the fuel filter is usually formed from cloth or made of a synthetic resin so as to have a mesh-like form, and can reliably remove foreign matter such as water and dust particles from the fuel.
  • the fuel filter is disposed within a fuel tank as noted above.
  • the fuel filter is normally mounted within the fuel tank before the assembling thereof, and it is disposed within the fuel tank when the fuel tank is assembled.
  • the fuel tank normally consists of upper and lower panels, and is assembled by welding these two panels together. Therefore, in the operation of assembling the fuel tank, the fuel filter is liable to be burned or otherwise damaged by means of spattered molten metal during the welding operation.
  • the invention hs been made in light of the above facts, and its object is to provide a fuel filter for a motor vehicle, which is safe from damage by means of any spattering of molten metal or the like which may occur during the welding process.
  • a fuel filter which comprises a main filter element for removing foreign matter and an auxiliary filter element consisting of a metal net covering the main filter element.
  • the metal auxiliary filter element provides shielding against any spattering of molten metal or the like which may occur during the welding process.
  • the main filter element is thus reliably protected against spattering of the molten metal or the like so that it will not be damaged thereby.
  • FIG. 1 is a side view, partly in section, showing an embodiment of the fuel filter according to the invention
  • FIG. 2 is an exploded perspective view showing the filter shown in FIG. 1;
  • FIG. 3 is a perspective view showing the fuel filter of FIG. 1 mounted within an assembled fuel tank.
  • FIG. 3 illustrates an embodiment of the fuel filter for a motor vehicle fuel tank according to the invention.
  • a fuel filter 10 is disposed within a fuel tank 12. Fuel within the fuel tank 12 is filtered through means of the fuel filter 10 for removal of foreign matter, such as, for example, water and dust particles, before being withdrawn through a fuel pipe 18.
  • the fuel tank 12 consists of a lower panel 14 and an upper panel 16 welded thereto.
  • the fuel filter 10 is mounted upon the upper panel 16 together with the fuel pipe 18 before assembly of the fuel tank 12, that is, before the welding of the lower panel 14 to the upper panel 16.
  • the fuel pipe 18 is inserted through and secured to the upper panel 16.
  • the fuel filter 10 is fitted upon an end of the fuel pipe 18 and then mounted below the upper panel 16. When the upper panel 16 is subsequently welded to the lower panel 14, the fuel filter 10 is disposed between the upper and lower panels 16 and 14.
  • the fuel filter 10 consists of an inner filter member or assembly 20 and an outer filter member or assembly 22.
  • the inner member 20 has a substantially cylindrical body portion 24 and a mounting portion 28, and consists of a one-piece molding of a synthetic resin.
  • the body portion 24 has an opening 24a at one end which extends in the axial direction thereof. It has an outer flange 26 surrounding the opening 24a, and the mounting portion 28 is united to the flange 26.
  • the lower surface of the flange 26 has an annular raised portion 26a (see FIG. 1), thus partly increasing the outer diameter of the body portion 24.
  • the mounting portion 28 is united to flange portion 26 by means of a reduced thickness portion 30. It is inserted through the opening 24a of the body portion 24 so as to be affixed to the same by deforming or folding the reduced thickness portion 30.
  • the mounting portion 28 has a through hole 32 defined within an axial sleeve member through which the fuel pipe 18 is to be inserted, and a holding portion 34 which is coaxial with the through hole 32 and through which the fuel pipe 18 can also be inserted, the through hole 32 and holding portion 34 being used for mounting the fuel filter upon the fuel pipe 18.
  • the body portion 24 of the inner member 20 has a plurality of circumferentially arranged openings 35 defined by means of ribs 36, and a main filter element 38 is installed within the openings 35.
  • the main filter element 38 consists of a nylon net having excellent water separation and fuel withdrawal performance characteristics.
  • the outer member 22 is a substantially cylindrical one-piece molding of a synthetic resin and can accommodate the inner member 20.
  • the outer member 22 has an opening 40 defined within one end thereof and extending in the axial direction.
  • the raised or flanged portion 26a of the inner member 20 is press fitted within the opening 40, so that the outer member 22 is affixed to the inner member 20 with the body portion 24 of the inner member 20 acommodated within the outer member 22.
  • the outer member 22 has a plurality of circumferentially arranged openings 42 defined by means of ribs 44.
  • the openings 42 extend substantially over the entire length of the outer member 22.
  • Each opening 42 has a greater area than each opening 35 of the inner member 20.
  • An auxiliary filter element 46 is installed within the openings 42.
  • the auxiliary filter element 46 is a stainless steel net and has excellent fuel withdrawal performance characteristics.
  • the inner member 20 is assembled with the mounting portion 28 mounted within the body portion 24.
  • the outer member 22 is assembled upon the inner member 20 with the raised or flanged portion 26a of the inner member 20 press fitted within the opening 40 of the outer member 22 and the body portion 24 of the inner member 20 disposed within outer member 22.
  • the fuel filter 10 is mounted upon the fuel pipe 18 with the fuel pipe 18 inserted through the holding portion 34 of the inner member 20 and the through hole 32 of the sleeve of the mounting portion 28 into the inner member 20.
  • the auxiliary filter element 46 reliably protects the main filter 38 against any spattering of molten metal or the like which may occur during assembling of the fuel tank 12, that is, during welding of the upper panel 16 to the lower panel 14. Furthermore, the auxiliary filter element 46 is maintained safe from being burned or damaged by means of spattered molten metal or the like because it is made of stainless steel.
  • the fuel filter 10 can be disposed within the fuel tank 12 without being damaged when the fuel tank 12 is assembled.
  • the fuel filtering area of the auxiliary filter element 46 of the fuel filter 10 is larger than the fuel filtering area of the main filter element 38, substantially no fuel withdrawal pressure loss is generated as a result of the installation of the auxiliary filter element 46 about the primary or main filter element 38.
  • the fuel filter 10 is characterized by having the mounting portion 28 to be mounted upon the fuel pipe 18 integral with the inner member 20, the number of components is reduced so as to reduce the manufacturing cost thereof.
  • the fuel filter comprises a main filter element for removing foreign matter and an auxiliary filter element consisting of a metal net covering the main filter element, so that the latter will not be damaged due to spattering of molten metal or the like during a welding operation of the assembly process of the fuel tank.
